Karl Stefanovic is being investigated by police following claims made by a waiter at a charity event, who allegedly says he was touched.

The waiter alleges Stefanovic, aged 48, touched him at a Mercedes-Benz melanoma charity fundraiser in Brisbane.

The Today show host attended the gala with his wife Jasmine, aged 38, in August.

Queensland Police told the  Courier Mail  that they were investigating an alleged assault said to have taken place on August 20.

“Queensland Police are investigating a report regarding the alleged assault of a man at a Newstead business during an event on Saturday, August 20,” a spokesman said.

“As investigations are ongoing it would be inappropriate to comment further.”

Stefanovic has not been charged.

The six-hour event saw Karl raise $290,000 for melanoma research.
